I haven't read all the comments here yet, but I'm going to throw this out anyway... My confidence in the author took a hit at the point he called a PDP-11 a "mainframe". One would think a computer scientist would know what computers fall into what "generation". I guess "history of computation" is just not taught as part of such a degree anymore...? But...I decided to read on, thinking maybe things would get better, and to give him the benefit of doubt. I think somewhere in there was maybe a few points to think about, but ultimately it almost looks like he has some weird problems with "separation of concerns", and maybe doesn't understand why that would be a bad thing for scaling... ...which again, I find odd for a computer scientist. Furthermore, he seems to ignore the great amount of improvements and changes which have occurred in the database software/engine and server world; today's DBs and DB systems are -nothing- like they were back in the early 90s when I started my career (as a fresh high-school graduate). Yeah, we still used VT-100 terminals (then quickly transitioned to PCs - running VT-100 terminal emulators, of course), and things were starting to transition to PC apps communicating to the servers - and I am sure there were SQL injection issues (and no, we didn't think about that) - but things have, over the decades (yeesh - getting old here!) have changed for the better! Could they be better? Certainly! Are there things the DB server could be doing to make life easier for the app? Yes (and some of this has been implemented - ie, when developed properly, your queries can be "sanitized" at the DB server level - but you know, you should still do this at the app and browser level too - just in case). Realtime updates and notifications? That's pretty much there as well - but ultimately, a lot still has to be done at other levels. ...and that's not a bad thing, imho.
